Abstract:

Free-flight tests were conducted in the Defence Research Establishment Valcartier DREV aeroballistic range on a full-scale MPB-IID BDU-5003B MOD 1 bomb at subsonic velocities. All the main aerodynamic coefficients and dynamic stability derivatives were very well determined using the six-degree-of-freedom single- and multiple-fit data reduction techniques. The free-flight data shows that this bomb is dynamically unstable at low angles of attack. The second order pitch damping coefficient, the yaw axial force term as well as side moments were also reduced. Wind tunnel, Open Jet Facility experimental results and full-scale aircraft free-flight trials were compared with the aeroballistic ones.
